The answer to the question
The answer is D. (7x-5)= 2 and (3x-2)=1 and 1 - 2= 1
Hi!
Rules for solving 30-60-90 triangles are as follows:
* The hypotenuse is double the short leg.
* The short leg times √3 is the long leg
To solve then, we divide 4√21 by √3 and get 4√7. That is x, and to get y we multiply by 2. That is 8√7.
Hope this helps! :D
Answer: Let the number be x
four times a number = 4x
16 less than four times a number = 4x - 16
4x - 16 = 64
Keeping constants on one side
4x = 64 +16
4x = 80
x = 80/4 = 20
The number is 20

Answer:
24 + 8i
Step-by-step explanation:
t = 4
u = 6 + 2i
t x u
= 4 ( 6 + 2i )
= 24 + 8i
